Worked in Quality Control 40+ years in a Lawn Mower MFG plant and we purchased PM parts, I was always fascinated in the process and inspecting them, never had the opportunity to actually see such an operation

Hi Numa, In PM gear parts ,tooth density and part overall density will be same ?

This is well and truly one of those marvels of manufacturing. Taking the cost of a plastic injection molded part and strength of a machined part. And while not having the exact same properties of both, it is a well worthwhile compromise. If it could even really be called a compromise.

Wouldn't this make herringbone gear production just as easy as any other gear type? Obviously, after taking into account the initial setup with the right molds, pressures, accounting for the different angles of the gear teeth, maybe even having to make it a two-stage press process, etc.

@JohnHWelch63 2 жыл бұрын

The sintering process doesn't necessarily get the parts to specs. The need to go on a sizing press after or sometimes come off the sinter furnace and go through a temper furnace. Some parts are done at that point and some need further work such as lathing, grinding, electroplating.

@ma61king 9 ай бұрын

I did wonder how dimensionally accurate those parts were, I was thinking this might be a good substitute for metal die casting. The splined gears they showed here here made me think they must be able to get stuff pretty close to perfect

@@ma61king I operate a sinter furnace. The tolerance varies depending on what the part is used for. We mostly make parts for automotive use, like gears and gerotors for fuel pumps. I can tweak my furnace to change the part size right down to a matter of micrometers by adjusting either temp or belt speed, but not every single part will be exact right down to the micrometer. They need to be worked further on a sizing press. At least where I work there is nothing we manufacture that doesn’t need further work after sintering.

@ma61king 9 ай бұрын

@@JohnHWelch63 Interesting, does the sizing press operate while the parts are still hot enough to be in a plastic state?

@JohnHWelch63 9 ай бұрын

@@ma61king They can go on the sizing press at any time from right off the furnace until days later when they are fully cooled. Doesn't matter. I've never seen them work them on the press right away though. After they come off the furnace the sizing press is usually working a couple of orders ahead of them, so they always end up sitting for a while before sizing. Granted, I'm talking about the parts we make. Other plants might make parts that require different processes, IDK.

Can hot Isostatic pressing be used to remove the porosity you mention?

@canys24bb78 2 жыл бұрын

it can just reduced the porosity. The thing is to stay below the mT.

RTX announced yesterday they've discovered rare defects in their powdered metal production in their NEO geared turbofan Airbus 320 engines. They require advanced inspections, and it only affects engines already in the field. What type of rare defect could get past part acceptance and process control testing?

@sadiporter2966 7 ай бұрын

a powder was in the powder mixture that wasn't supposed to be there.

@nuclearrabbit1 7 ай бұрын

@sadiporter2966 Yeah, thanks for the response. My post is obviously outdated. Turns out this wasn't as rare as initially believed. Many inspections and a lot of downtime for most of these engines as combustion chambers are replaced. Huge issues for many airlines, as well as RTX and Pratt. Not sure how a foreign substance gets into a powdered metal formula. I bet there is an internal investigation that will never see the light of day.

You keep saying you are using different "atmospheres"... atmosphere is an oxymoron for gas doesn't form spheres gas takes the shape of its container... so what do you mean when you say you are using different atmospheres (sphere shaped gas)?
